If you have an X11 implementation without xv support, OpenGL is a viable alternative. </p><p> Unfortunately not all drivers support this feature. The Utah-GLX drivers (for XFree86 3.3.6) support it for all cards. See <a class="ulink" href="http://utah-glx.sf.net" target="_top">http://utah-glx.sf.net</a> for details about how to install it. </p><p> XFree86(DRI) 4.0.3 or later supports OpenGL with Matrox and Radeon cards, 4.2.0 or later supports Rage128. See <a class="ulink" href="http://dri.sf.net" target="_top">http://dri.sf.net</a> for download and installation instructions. </p><p> A hint from one of our users: the GL video output can be used to get vsynced TV output.
